WordPress.com 2.5 Essential Training at lynda.com Online Training Library® is a set of training videos by Maria Langer (who also happens to be a professional helicopter pilot) that walk through the setup and use of WordPress as a blogging tool. Sadly, the title of this set of videos might be a bit misleading (though the title does indeed say WordPress.com, I was taken by the version number in the title) since the videos are tailored for WordPress.com blogs and not for self hosted WordPress.org blogs. However, a few of the initial videos are offered for free download and the only option for purchase of the full set is via a monthly subscription for $25 which would give the user access to all the videos on lynda.com. There are plans to sell the videos as a CDROM for purchase but those are not available as of this post.
The videos are aimed towards the basics of blogging and range in topics from setting up a blog on WordPress.com to creating and maintaining posts, pages, categories, adding multimedia, choosing and setting up themes, managing users and participating in the blogosphere.
